Hi, is it possible to do a halt whenever some instance variable is written?
Soon… I am working on it.
Make a class TT with ivar ‘tt’, method
tt
tt := 1.
Then we can define a meta-link to call "Halt now”:
| link |
link := MetaLink new
metaObject: Halt;
selector: #now.
This we can install on the Slot itself:
(TT slotNamed: #tt) link: link.
If we now call
TT new tt
it will tell you that we need to implement #write:to: in LinkWrapper… ;-)
Which means a lot of the basic machinery is working!
Next week...
